madanfhard.-fihener-Qthertsuitableweariet sisting material, which isadapted to be mounted upon the rod 18 with one end 20 thereof abuttingthe free end of the tube 17. The opposite end of this collar is, in thisinstance, tapered as shown at 21. In order to compress or clamp thiscollar upon the rod 18 and to connect the collar to the tube 17 so thatwhen the rod and tube move relatively to each other, there will also bea relative movement between the collar and rod, I have provided aclamping sleeve 22 threaded upon the free end of the tube 17. Theinterior diameter of the clamping sleeve is varied so that a partthereof will cooperate with the tapered end 21 of the collar 19 tocompress the latter upon the rod. In the form shown, the sleeve isprovided with an interior tapered portion 23 which cooperates with thetapered portion 21 for the purpose described. It will be apparent,however, that it will not always be necessary to have tapered surfacesupon both the collar and sleeve in all instances, as the same resultmight be secured by the provision of a collar of constant externaldiameter, relying upon the tapered sleeve alone to produce the clampingor compressing action. On the other hand, the collar might be providedwith a tapered end and an internal shoulder or similarly formed reducedportion provided in the sleeve to cooperate with this ta-' pered end ofthe collar and cause the latter to be clamped tightly about the rod.

It will be obvious that when the sleeve is adjusted upon the tube 17 bymeans of the threaded connection therewith, any desired amount offriction may be created between the rod and the collar and as when therod is withdrawn from the tube, the collar is held tightly against theend of the tube by the sleeve 22, the rod must move relatively to thecollar and hence any friction between these two elements will tend toresist this movement. Thus while the window may be grasped positivelyand moved to any desired or predetermined open position, the frictionbetween the parts will hold the window in that position until it ispositively closed by the operator. Thus the friction will be greatenough to hold it against the wind or any force which might tend toaccidentally close it. Moreover, if due to constant usage and wear, itis found that the friction between the parts is no longer sufficient,the sleeve 22 may be further adjusted upon the tube 17 and the frictionincreased the desired amount. A shoulder 24 may be provided on the rod18 to more or less positively hold the window in any desired position asconsiderable resistance will be oifered to the passage of this shoulderthrough the fiber collar 19.

In Figs. 7 and 8 I have shown a modified form of my invention, whereinthe tube 17 is provided with two longitudinal slots 17 extending a shortdistance from the free end thereof and is provided at this end with atapered portion 25 which cooperates with a tapered portion 23 of asleeve 22 In this form of my invention I have omitted the While I haveshown and described in de- 7 tail some preferred embodiments of myinvention, it will be obvious that the same is not limited to thedetails shown, but is ca pable of many modifications and variationswhich come within the spirit of the invention and the scope of theappended claims.

What I claim is:

1. In a casement window adjuster, an eX- tensible member comprising atelescoping tube and rod, a split collar mounted to move with one ofsaid members and means to cause said collar to frictionally engage theother member to resist relative movement of the rod and tube, saidcollar being generally of cylindrical shape but having a tapered end,and said means comprising a second collar having an interior formationcorresponding tothe split collar and movable relatively to the splitcollar to compress the latter.

2. In a casement window adjuster an extensible member comprising a tubeand a rod slidable therein, a split collar mounted upon the rod andabutting the tube at one end thereof, said collar being generally ofcylindrical shape, but having the end remote from the tube tapered, asecond collar adapted to threadedly engage the tube. end and encirclethe split collar, said collar having an interior bore of a shapecorrespond ing to that of the split collar and being adapted to compressthe latter upon the rod, and adjusted toward the'tube by its threadedconnection therewith.

3. In a casement window adjuster, an ex tensible member comprising atube and a rod slidable therein, a compressible split collar mounted onthe rod and adapted to abut against the tube at one end,.and an outercollar threaded upon the tube embrac' ing said compressible collar toconnect it to the tube and to cause it to frictionally en gage the rod,said collars being complementally shaped so that the when the outercollar is threaded on the tube the inner collar will be compressed.

4. In a casement window adjuster, an extensible member comprising a tubeandlai rod slidable therein, a compressible split collar mounted on therod and adapted to abut against the tube at one end, and having itsother end tapered, and an outer collar having a bore corresponding tothe shape of the split collar embracing said compressible collar toconnect it to the tube and adjustable to cause it to frictionally engagethe rod.

5. I11 a casement window adjuster, an eX-' tensible member comprising atube and a rod slida-ble therein, a compressible collar mounted on therod and adapted to abut against the end of the tube at one end, andhaving its other end tapered, an outer collar embracing the compressiblecollar, having a bore adapted to cooperate with the tapered end thereof,and means to connect the outer collar to the tube.

6. In a casement window adjuster, an extensible member comprising a tubeand a rod slidable therein, a compressible collar mounted on the rod andadapted to abut against the end of the tube at one end, and having itsother end tapered, an outer collar embracing the compressible collar,having a tapered bore adapted to cooperate with the tapered end thereof,and means to connect the outer collar to the tube.

7. In a casement window adjuster, an extensible member comprising a tubeand a rod slidable therein, a compressible collar mounted on the rod andadapted to abut against the end of the tube at one end, and having itsother end tapered, and an outer collar embracing the compressiblecollar, having a tapered bore adapted to cooperate with the tapered endthereof, and adjustably connected to the tube, said adjustment beingadapted to vary the frictional engagement between the compressiblecollar and the rod.

8. In combination, a Window frame, a hinged window, a rod connected toone end thereof and a tubular member connected to the other, said memberhaving a bore slidably receiving said rod, a split collar on the rodhaving one end thereof abutting the adjacent end of the tube and havingthe other end tapered, an outer collar threaded upon the tube arrangedto embrace the split collar and having a tapered bore to cooperate withthe tapered end of the split collar to compress the latter upon the rodwhen the outer collar is drawn toward the tube by means of its threadedconnection therewith.

In witness whereof, I have hereunto set my hand this 4th day ofNovember, 1921.
